Q. Who is Mr. Smarty Plants?

A: There are those who suspect Wildflower Center volunteers are the culpable and capable culprits. Yet, others think staff members play some, albeit small, role. You can torture us with your plant questions, but we will never reveal the Green Guru's secret identity.

Title: Identity of plant that smells like oranges in Alpine, TX
Answered by: Nan Hampton and Joe Marcus

QUESTION:

There are patches of flat bushy like plants in lawn, smells like orange. Areas may be 10" and spreading, but when pulled has small root. How can I get rid of this plant and what is it?

ANSWER:

This sounds like one of the Crotons.  There are several species that occur in Brewster County and all have a characteristic odor, much like oranges, when the leaves are crushed.  The most likely one is Croton monanthogynus (Prairie tea).  Here are more photos and information from University of Texas School of Biological Sciences, Texas A&M AgriLIFE Extension and from Missouri State University.

There are also:

Croton lindheimerianus (Threeseed croton).  Here are photos from the Samuel Roberts Noble Foundation.

Croton pottsii var. pottsii (Leatherweed)

Croton suaveolens (Scented croton)

Croton texensis (Texas croton)

Croton incanus (Torrey's croton).  Here are photos and more information from Texas A&M Aggie Horticulture.

Croton fruticulosus (Bush croton)

The best way to get rid of the plant is just what you have been doing—pull it up.  On the other hand, you might consider waiting until after it's dropped its seeds.  Crotons are often called doveweeds for their important role in providing essential forage for doves, quail and other ground-feeding birds.

If this isn't the plant you have in your lawn, take photos of it and then visit our Plant Identification page where you will find links to several plant identification forums that will accept photos of plants for identification.
